Hey all,
  My current (and only) primary was made from several (5 or 6 maybe)
sections of 22ga wire that I got off old television yokes.. I spliced the
sections of wire together by twisting them (an old splice I saw in a book
from the 20's) and then soldiering the slpice.. when the coil was completely
wound, I just varnished the crap out of it and so far it has worked just
fine.. I can draw 12" streamers and I get no arcing to the primary (yet)..

Yer in luck I tell ya....  :)   You can just take a jewelers file, and file
the wire to a sloping point.  file on one side of the wire only, and dont
remove the insulation on the other side.  File it flat but sloping at
an angle to create a long wedge shape maybe 1/2" long.  Then file
the other end the same way.  Fit the two ends together with the
filed portions touching, and you'll see it fits smooth with no bump.
Then fire up your soldering iron, and tin both sections.  The solder
won't stick to the other side, where there's insulation.  Thus,
the solder will stick only to the filed slope, which is what you want.
After both ends are tinned thinnly, overlap the ends, and heat the
joint with the iron, so it solders together, and you'll have a perfect
joint.
